摘要
从储层精细描述的角度 ,对储层、沉积微相进行精细研究。根据砂体在纵向上的沉积韵律变化特征和平面上的展布特点以及位于构造的具体位置 ,结合文南油田和马厂油田的生产实例分析 ,对中高含水期油田的剩余油分布规律进行研究和挖潜。这对增加老油田的可采储量 ,提高老油田的最终采收率 ,具有广阔的应用前景。
In this paper,the formation sedimentary microfacies were discussed by fine formation description.The retained oil distribution rules of middle-high water cut stage oil fields was studied in light of vertical changing characteristics of sandstone sedimentary rhythm,horizontal distribution features and precise location in oil trap,combined production examples in Wennan and Machang Oilfields,which have excellent prospect in increasing recoverable reserves and enhancing ultimate oil recovery factor.
